Without a doubt, one of the biggest developments in the MCAD world in the past few years has been 3D printing (also known as additive manufacturing). Until relatively recently, though, the cost of the 3D printing machines was cost prohibitive for all but large companies. To a large extent, costs have been plummeting, but there are machines that cost more than a million dollars. However, that is changing with the advent of relatively low-cost desktop 3D printers.

3D printers sound cool, and to a large extent they are. But, before running out to buy one, there are a few things to keep in mind. Currently, a machine will set you back $500 to $5,000, plus $40 to $100 for a roll of plastic filament (think Weed Wacker) for producing parts. Also keep in mind that producing one small object could take hours, and end up costing much more than buying it. Don’t forget, too, that you need some technical know-how to make it all work, including how to create a solid model with a CAD tool. As I have maintained for some time, with all the online 3D printing services that are available, why buy when you can rent. Check out my blog post on this sentiment from last year entitled, “3D Printing Goes Retail: Why Buy When You Can Rent?”

That’s why I have said that the first low-cost devices were more fun than functional, and appealed to DIYers, hobbyists, and early adopters. All that is changing as the technology matures, prices come down, more materials become available, and part quality vastly improves.
